The Pearl Coast
The Grand Empire of Vailia lasted for about 1500 years but has collapsed by the current day. Once the crown jewel of the southern seas, the crumbling island nations of Old Vailia sit thousands of miles to the southwest of their offshoot, the Vailian Republics (a colonization effort that took place few centuries before). They are renowned for their great culture and history of accomplishments, though the rest of the world considers them to be far past their prime. The nations that once made up the empire are engaged in a continuous war for dominance that has been going on (and off, and on again) for over two hundred years.
The Dyrwood calendar (Anni Iroccio) is based on earlier Vailia calendar. The Vailians pioneered cartography and theories of the world's shape.
